What is the reason why the heating effect of the air conditioner is not good

One reason why the heating effect of the air conditioner is not good is because the air filter has too much dust and the vents of the internal and external units are blocked by foreign objects. The function of the filter screen is to adsorb the dust in the air, if the dust is too much and not cleaned in time, the air circulation will be blocked, resulting in the reduction of the air outlet volume, so that the heat in the machine can not be brought out by the flowing air in time, resulting in insufficient heat production, this is not a fault, it belongs to the maintenance of the air conditioner, just remove the air filter regularly to clean, it can be restored to normal. Fluoride deficiency can also be a contributing factor.

At present, most people use heat pump type or heat pump plus auxiliary electric heating type air conditioner. Both air conditioners work by using freon to absorb heat from the outside air as it evaporates. When the outside temperature is low, the temperature difference with the evaporation temperature of freon is smaller, and the heat exchange effect becomes worse, and the hot air is less.

Hello: This is the case.

Generally speaking, the heating effect of air conditioners is not good, partly because the air filter has too much dust and the vents of the internal and external units are blocked by foreign objects. The function of the filter screen is to adsorb the dust in the air, if the accumulated dust is too much and not cleaned in time, the air circulation will be blocked, resulting in the reduction of the air outlet volume, resulting in the heat in the machine can not be brought out by the flowing air in time, resulting in insufficient heat production, this is not a fault, it belongs to the maintenance of the air conditioner, just take off the air filter regularly to clean, it can be restored to normal.

Fluoride deficiency is one of them. At present, most of my friends use heat pump type or heat pump plus auxiliary electric heating type air conditioner. The working principle of these two air conditioners is that when the freon evaporates, it absorbs heat from the outside air, and when the outdoor temperature is low, the temperature difference with the evaporation temperature of the freon is smaller, and the heat exchange effect becomes worse, and the hot air is less.

Therefore, if it is an old model, the service life is longer, the wear of the compressor is larger, and when the outdoor temperature is below 0, the heating effect of the York air conditioner is difficult to be satisfactory. In addition, if the nut at the copper pipe horn is not tightened during the installation of your own air conditioner, or the machine has been moved, it can be considered as a lack of fluorine.

In addition to this, line control failures are also common. For example, if the external unit is not working, it is most likely due to the failure of the capacitor, temperature probe or motherboard. The fault mainly occurs on the four-way solenoid valve or its control circuit, and it may also be the AC contactor, thermostat and over-temperature fuse of the electric heater and its power supply circuit, all of which need to be detected by the master.

Hope it helps!

Some friends report that their home air conditioners often have poor heating effects, why does this happen?

There are three possibilities for poor heating of air conditioners:

1. The heating effect of the air conditioner is deteriorated due to the lack of refrigerant, and the refrigerant needs to be charged at this time.

2. The outdoor temperature is too low, resulting in the refrigerant being unable to absorb heat from the outside, and under normal circumstances, the heating effect will be greatly reduced when the outdoor temperature is lower than minus 5 degrees.

3. Check valve failure, when the air conditioner is heating, the check valve reversely isolates the refrigerant, so that the refrigerant flows to the main capillary through the auxiliary capillary, which further reduces the pressure and improves the heating effect.

What to do if the heating effect of the air conditioner is not good:

1. Clean the air conditioner fan blades.

The air conditioner needs to be cleaned regularly, and if the fan blades are dirty, it will also affect the heating effect of the air conditioner.

2. Check whether the refrigerant is insufficient.

Check whether the refrigerant of the air conditioner is insufficient, if the refrigerant is insufficient, add the refrigerant to crack the hood and use it normally.

3. Check whether the air conditioner is faulty.

Check whether there are any parts of the air conditioner damaged, if there is any damage, after the replacement parts are repaired, the air conditioner can be used normally.

4. Air conditioning power.

Generally, the power of household air conditioners is limited, and when the outdoor temperature reaches about minus 5-10 degrees, it is normal for the heating efficiency of air conditioners to be relatively poor.

Reasons for the heating effect of air conditioning: low outdoor temperature or poor electricity environment, too small heating power of air conditioning, no electric auxiliary function, poor heating effect, too much dust in the air conditioning filter, and old air conditioning.

1. Low outdoor temperature or poor electricity environment: If the outdoor temperature is too low, the air conditioner will not work normally, and when the outdoor temperature is too low, the outdoor unit will not be able to defrost, and the air conditioner will not be able to heat. In addition, if the voltage is too low, it may directly affect the cooling and heating effect of the air conditioner.

2. The heating power of the air conditioner is too small: the size of the room is different, and the number of applicable air conditioners is also different. If the room is relatively large and the number of horsepower to choose the air conditioner is relatively small, it is easy to cause this problem.

3. No electric auxiliary function: After market research, the main reason for the poor heating effect of many air conditioners is that there is no electric auxiliary heating function, and the situation of old-fashioned air conditioners is very prominent.

4. The heating effect is not good, and the air conditioning filter has too much dust: the air conditioning air filter has too much dust, and the vents of the internal and external units are blocked by foreign objects. The function of the filter is to adsorb the dust in the air, if the dust is too much and not cleaned in time, the air circulation will be blocked, resulting in the reduction of the air outlet volume, resulting in the heat production in the machine can not be brought out by the flowing air in time, resulting in insufficient heat production.

5. The air conditioner is old: the air conditioner has been used for too long and the performance cannot keep up, so it is recommended to replace one.

What's the matter if the heating effect of the air conditioner is not good? What are the causes? How to investigate? The master will teach you how to repair!

The reasons for the poor heating effect of air conditioning are: 1. Evaporator failure. The evaporator of the air conditioner is installed outdoors, so it is easy to freeze and fail, which leads to frost in the air conditioner evaporator and poor heating effect of the air conditioner.

The solution is to check whether the defrost thermostat of the air conditioner is misaligned or in poor contact, and repair it after finding the fault.

2. The parts are faulty. The main function of the air conditioner check valve is to prevent the reverse flow of oil in the hydraulic system, if this part fails, then it is easy for the heating effect of the air conditioner to decrease. Its workaround is to replace it.

3. There is no regular cleaning. If the dust inside the air conditioner is not cleaned regularly, the vents of the internal and external units will be blocked by dust, which will seriously affect the heating effect of the air conditioner. Its solution is to clean the air conditioner dust regularly every three months.

If the cooling effect of the air conditioner is not good, we need to find out what causes it. When using air conditioners in winter, there are also many users who report that the heating effect of air conditioners is not good, and the indoor temperature is relatively low after a long time. So what is the reason for the poor heating effect of the air conditioner?

Is there any good way to solve it?

1. What is the reason for the poor heating effect of air conditioning?

1. If the number of air conditioners selected does not match the area of the room, the heating and cooling effect will not be good, for example, the area of the room is more than 20 square meters, and the air conditioner below the number of horses is selected, and the heating effect is not very good. In this case, it is necessary to choose a 2 hp air conditioner to achieve the heating effect.

2. If the heating effect is not good, you should also consider whether there is a lack of refrigerant. Some people may not understand that refrigerant is not needed when it is cooling? In fact, no, refrigerant is also needed when heating, and the refrigerant of air conditioning is mainly freon, if it is missing, even if the temperature of the air conditioner is adjusted to more than 30 degrees, the room will not be hot, so the same as the refrigeration effect, you need to add freon to the air conditioner in time.

3. In winter, if the indoor temperature is relatively low, turning on the air conditioner will have no effect, which is caused by objective reasons. In particular, some fixed-frequency air conditioners will seriously affect the heating effect. In northern cities, the outdoor temperature is more than ten degrees below zero, which is too cold, and the effect of turning on the air conditioner is not particularly great at this time.

Second, what should I do if the heating effect of the air conditioner is not good?

1. Before turning on the air conditioner, you first need to clean the dust on the filter screen, because the dust will cause the air volume of the air outlet to be relatively small, so that you can't feel the heat. Therefore, it is necessary to clean it when it is used, or ask a professional to carry out deep cleaning through professional means, which can also effectively ensure that the heating effect is better.

2. To replenish freon in time, this is the most common fault, if the air conditioner has been used for a long time, the lack of freon will reduce the thermal cycle, plus it can meet the effect of heating.

Summary: When the air conditioner is turned on in winter, if we find that the heating effect is not good, we should consider whether it is because of the lack of freon, or the air conditioner has not been cleaned for a long time, and there is too much dust at the air outlet, as long as it is cleaned, it will be effective.

Air conditioners not only have the function of cooling, but also the heating function is very popular, which can increase the temperature in the room and ensure a normal home life, but it is also necessary to use the air conditioner correctly. So what are the reasons for the poor heating effect of air conditioners, and what should be paid attention to in air conditioning heating, do you know about it? Now let's take a look.

1. What is the reason for the poor heating effect of air conditioning?

1. The indoor temperature is too low, which causes the heating to be inhibited; 2. The environment of indoor electricity is poor, which is not conducive to air conditioning and heating; 3. The power of the air conditioner itself is not enough to release enough heat; 4. The filter inside the air conditioner has not been cleaned, and too much dust has accumulated; 5. The air conditioner is not designed with electric auxiliary mode, and the heating is not obvious.

Second, what should be paid attention to in air conditioning heating?

1. The power is different depending on the brand and model of the air conditioner, if you want to make the air conditioner play the maximum role, you need to measure the size of the room to be installed with the air conditioner, so as to determine the number of air conditioners needed. If the indoor sealing effect is relatively poor, it will affect the heating of the air conditioner, and the indoor temperature will be full, or even stagnate.

2. In the process of using the air conditioner, it is best to control the temperature of the air conditioner at about 20 to 23 degrees, which is enough to bring yourself a comfortable home life, and it will not waste too much electricity. Moreover, it is important to know that if the air conditioner is at the lowest or highest temperature for a long time, it is easy to reduce the life of the air conditioner.

3. During the period when the air conditioner is turned on, it is necessary to replace the indoor air to ensure that there is enough fresh air in the room, so that the user's health can be better protected. If you do not change the air for a long time, the room will be in a situation of lack of oxygen, and bacteria and viruses will also increase.

What are the reasons for the poor heating effect of air conditioners, and what should be paid attention to in air conditioning heating, I will introduce it here, do you understand? The heating effect of the air conditioner is not good, so it is necessary to find the cause and deal with it in time, so as not to affect the future use.

<> reason why the heating effect of the air conditioner is not good may be due to the fact that the power of the air conditioner is too large or too small, or the room area is too large, you can replace the high-power air conditioner and develop the habit of cleaning the filter regularly. Be sure to remember to disconnect the power supply during the cleaning process, and do not clean the filter with dish soap, laundry detergent, etc., so as not to deform the filter.

1. When the outdoor temperature is lower than 0 degrees Celsius, the outdoor unit of the air conditioner will immediately frost, and when the user turns on the air conditioner for heating, it takes about 8-12 minutes to "remove the frost", and some users mistakenly think that the heating effect of the air conditioner is not ideal.

2. Due to improper use and maintenance by users, etc.

3. The reason why the air conditioner cannot work normally is because the electricity consumption increases greatly, which may cause the regional power supply voltage to be unstable or too low.

4. There may be a lack of fluorine, at this time we need to ask after-sales service personnel to check the fluoride. Most users use heat pump type or heat pump plus auxiliary electric heating type air conditioner.

5. The applicable area of air conditioning heating is smaller than the area of the room using air conditioning, resulting in the room temperature not rising ideally, that is, the customized heat is not enough. At this time, we need to use cloth curtains and spray-painted portrait partitions to reduce the room area; -5 degrees below it is recommended not to turn on the air conditioner, use auxiliary electric heating, use wall-hung boiler or heater; When using air conditioners, we try to avoid using air conditioners during peak hours.

6. The reason why Xian Minhong affects the heating effect of the air conditioner is because the outdoor temperature is below -5. The lower the outdoor temperature, the worse the heating effect of the air conditioner, and the actual heating is not enough.
